DOOR-OPERATING MEANS.

Divided and this application led August 6,

1913. Serial No. 783,390.

To all 'whom t may concern Be it known that I, GEORGE B. Koi-11,1112, acitizen -of the United States, residing in Philadelphia, Pennsylvania,have invented certain Improvements in Door-Operating Means, of which thefollowing is a speci- This invention relates to certain improvements inmeans for operating the doors of a passenger car, or other vehicle, andis a 'division of an application for patent filed by me o-n the 9th dayof April, 1913, under Serial No. 759,981, relating` to door and stepoperating mechanism.

One objectof the present invention is to provide simple and effectivemeans for opening and closing pivoted doors.

A further object of this invention is to actuate the doors from avertical shaft through cams which can be adjusted on the shaft.

These objects I attain in the following manner, reference being had tothe accompanying drawings, in which:

Figure 1 is a plan view partly in section on the line ca -a, Fig 2;showing the platform of a passanger car party broken away; Fig. 2 is avsectional elevation on the line Z-J), Fig. 1 with the cams in side view;Fig. 3 is an enlarged sectional view illustrating the two cams and theirrods; Fig. 4 is a plan view of one of the cams; and Fig. 5 is a detachedperspective view illustrating the rod and its connection with the pivotof the door.

Referring to the drawings, 1 is the body of a car.

2 is the platform, in the present instance, and 3, 4 are the doorslocated at one side of the platform mounted on pivots 5 and 6respectively. The doors are made in two parts and rods 7 are connectedto the outer section of each door and to a fixed point 8 at the roof ofthe platform so that when the doors are actuated the outer sections willbe properly guided into the open or closed position, but the usualupper' rail may be substituted for the bars without departing from theessential features of the invention.

9 is a vertically arranged operating shaft located at about the middleof the platform, in the present instance, and mounted in an upperbearing 10 which is attached to the rail 11 which extends over theplatform, and

mounted in a lower bearing 12 located in the floor 13 of the platform.Adjustably secured to the shaft by set screws and located under thefloor are two cams 14 and 15 and at the upper end of the shaft is anoperating handle 16. Each cam has a single slot therein.

18, 18 are two rods.V One rod extends over the upper cam and the otherrod extends under the lower cam. The cams are arranged back to back.Both rods have slotted heads 19 and the shaft 9 extends through the slotin each head and acts as a guide for the inner ends of said rods.

Secured to the lower end of each pivot 5 and 6 is an arm 20. One rod 18is secured to one arm 20 and the other rod 18 is secured to the otherarm 20. The head 19 has a pin 21 which extends 'into the groove in theupper cam 14 and the lower rod has a pin 22 which extends into thegroove inthe lower cam so that when the operating shaft is turned thedoors are opened or closed.

The cams are so formed, in the present instance, that when the doors areclosed the pins are located in the concentric portion of the groove ofthe cams and when the cams are turned in the direction of the arrow,Fig. 1, the door 3 will be opened first, followed by the other door 4.If the direction of movement of the shaft is reversed then the door 4will be opened first, followed by the door 3. This construction enablesthe operator to open either' one of the doors, or both of them, with oneoperating handle.

By mounting the cams independently on the shaft, I can locate the shaftat any point on the platform or I can pivot the doors at either edge andthe cams can be set at the proper position after the shaft is locked.

The invention relates particularly to the means for operating doors andthe companion application hereinbefore referred to relates to the meansfor operating the steps located at one side of the platform below thedoors. v

As illustrated in Fig. 2, the step is pivoted at 23 and has a pin 24which extends through a slot in an arm 25 on an extension of the pivots5 and 6 of the doors so that as the doors are actuated the stepsopposite to said doors will be raised or lowered as the doors are closedor opened.

In the companion application, Serial No.

Patented May 30, 1916.

CIY

broadly the means for operating the engtrance and eXit doors of a carand also, indi this case, the construction in which a single cam isused. The present case is limited to the construction of two cams, onefor operating one door and the other for operating the other door.

I claim:

l. The combination of two vertically hung doors arranged side by side; avertical operating shaft located some distance from the doors; two camson said shaft; means for adjustably securing each of said cams to theshaft; and means controlled by the cams and connected to .the doors, thecams vbeing so shaped and arranged, on the shaft `that when the shaft ispartly turned in one direction one doo-r will be opened, followed by theother door as the movement is continued, and7 when the shaft is turnedin the opposite direction, the last mentioned door will -be opened andthe first mentioned door will follow.

2. The combination of a Hoor; two doors located above the iioor; a pivotfor each of said doors extending under the floor; an arm on each ypivotbelow the iioor; a vertical operating shaft extending through the floor;two cams on the operating shaft arranged back to back, both cams beinglocated under the floor; two rods having` slotted heads through whichthe operating shaftextends and by which they are guided; a pin on eachslotted head arranged to enter a slot in one of the cams, one rod beingconnected to an arm on the pivot of one door and the other rod beingconnected to an arm on the pivot of the other vdoor so that, on turningthe shaft, the doors will be opened or closed.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
